Wilhelm Steinitz vs Curt von Bardeleben
Hastings (1895), Hastings ENG, rd 10, Aug-17
————–
After 25.Rh7+ instead of resigning graciously Curt von Bardeleben got up and left the tournament hall without any further explanation … and he did not return but preferred to let his clock run down… only then Steinitz showed how White can announce a forced mate!
